I want to print with colorFabb nGen because the properties (heat resist, easy to print, robust) sound good for me.But I don't have good results.The print quality looks very good without stringing. But the parts are not strong. The parts are very brittle.I change my print settings especial the manual fan slider. Also I tested different part orientations - no strong impact.

These are my print settings:

print temp: 235 °C

Bedtemp: 70-85 °C (no different results)

resolution: 0,1 mm

print speed.: 40-50 mm/s

fan opening: 0 to 100 %

Somebody print colorFabb nGen on his Raise3D N1 and can tell me the settings?
